Prosecutors say they will pursue a premeditated murder charge against Oscar Pistorius as the Paralympic superstar openly wept in court Friday after being charged with shooting his girlfriend to death.

Pistorius was formally charged at Pretoria Magistrate's Court with one count of murder.

Reeva Steenkamp, a model and budding reality TV show participant, was shot and killed at Pistorius' upmarket home in an eastern suburb of the South African capital in the predawn hours of Thursday, sending the country reeling.

Pistorius stood with his face in his hands as he broke down in tears on his first court appearance.

The magistrate delayed Pistorius' bail hearing until next Tuesday and Wednesday and ruled that the 26-year-old Pistorius would be held at a Pretoria police station until then.
